The on-disk data structures from AIX are not known, also the filesystem
layout is not known. There is a msdos partition signature at the end of
the first block, and the kernel recognizes 3 small (and overlapping)
partitions. But they are not usable. Maybe the firmware uses it to find
the bootloader for AIX, but AIX boots also if the first block is cleared.
This is the content of the partition table:
# dd if=/dev/sdb count=$(( 4 * 16 )) bs=1 skip=$(( 0x1be )) | xxd
0000000: 0000 0000 0000 0000 0000 0000 0000 0000 ................
0000010: 80ff ffff 41ff ffff 1b11 0000 381b 0000 ....A.......8...
0000020: 00ff ffff 41ff ffff 0211 0000 1900 0000 ....A...........
0000030: 80ff ffff 41ff ffff 1b11 0000 381b 0000 ....A.......8...
Handle the whole disk as empty disk.
This fixes also YaST which compares the output from parted (and formerly
fdisk) with /proc/partitions. fdisk recognizes the AIX label since a long
time, SuSE has a patch for parted to handle the disk label as unknown.
dmesg will look like this:
sda: [AIX] unknown partition table
Tested on an IBM B50 with AIX V4.3.3.

This teaches dmi_decode() how to decode and save OEM Strings (type 11) DMI
information, which is currently discarded silently. Existing code using
DMI is not affected. Follows the "System Management BIOS (SMBIOS)
Specification" (http://www.dmtf.org/standards/smbios), and also the
userspace dmidecode.c code.
OEM Strings are the only safe way to identify some hardware, e.g., the
ThinkPad embedded controller used by the soon-to-be-submitted tp_smapi
driver. This will also let us eliminate the long whitelist in the mainline
hdaps driver (in a future patch).

In the "operation does permission checking" model used by fuse, chdir
permission is not checked, since there's no chdir method.
For this case set a lookup flag, which will be passed to ->permission(), so
fuse can distinguish it from permission checks for other operations.

Some filesystems may want to report different values depending on the path
within the filesystem, i.e. one mount is actually several filesystems. This
can be the case for a network filesystem exported by an unprivileged server
(e.g. sshfs).
This is now possible, thanks to David Howells "VFS: Permit filesystem to
perform statfs with a known root dentry" patch.
This change is backward compatible, so no need to change interface version.

Initialize module_subsys earlier (or at least earlier than devices) since
it could be used very early in the boot process if kmod loads a module
before the device initcalls. Otherwise, kmod will crash in
kernel/module.c:mod_sysfs_setup() since the kset in module_subsys is not
initialized yet.
I only noticed this problem because occasionally, kmod loads the modules
for my SCSI and Ethernet adapters very early, during the boot process
itself. I don't quite understand why it loads them sometimes and doesn't
load them other times. Or who is telling kmod to do so. Can someone
explain?

In spinlock_debug.c, the spinloops call __delay() on every iteration.

Make PROT_WRITE imply PROT_READ for a number of architectures which don't
support write only in hardware.
While looking at this, I noticed that some architectures which do not
support write only mappings already take the exact same approach. For
example, in arch/alpha/mm/fault.c:
"
if (cause < 0) {
if (!(vma->vm_flags & VM_EXEC))
goto bad_area;
} else if (!cause) {
/* Allow reads even for write-only mappings */
if (!(vma->vm_flags & (VM_READ | VM_WRITE)))
goto bad_area;
} else {
if (!(vma->vm_flags & VM_WRITE))
goto bad_area;
}
"
Thus, this patch brings other architectures which do not support write only
mappings in-line and consistent with the rest. I've verified the patch on
ia64, x86_64 and x86.
Additional discussion:
Several architectures, including x86, can not support write-only mappings.
The pte for x86 reserves a single bit for protection and its two states are
read only or read/write. Thus, write only is not supported in h/w.
Currently, if i 'mmap' a page write-only, the first read attempt on that page
creates a page fault and will SEGV. That check is enforced in
arch/blah/mm/fault.c. However, if i first write that page it will fault in
and the pte will be set to read/write. Thus, any subsequent reads to the page
will succeed. It is this inconsistency in behavior that this patch is
attempting to address. Furthermore, if the page is swapped out, and then
brought back the first read will also cause a SEGV. Thus, any arbitrary read
on a page can potentially result in a SEGV.
According to the SuSv3 spec, "if the application requests only PROT_WRITE, the
implementation may also allow read access." Also as mentioned, some
archtectures, such as alpha, shown above already take the approach that i am
suggesting.
The counter-argument to this raised by Arjan, is that the kernel is enforcing
the write only mapping the best it can given the h/w limitations. This is
true, however Alan Cox, and myself would argue that the inconsitency in
behavior, that is applications can sometimes work/sometimes fails is highly
undesireable. If you read through the thread, i think people, came to an
agreement on the last patch i posted, as nobody has objected to it...

Check driver layer errors.
Fix from: "Jun'ichi Nomura" <j-nomura@ce.jp.nec.com>
In blockdevc-check-errors.patch, add_bd_holder() is modified to return error
values when some of its operation failed. Among them, it returns -EEXIST when
a given bd_holder object already exists in the list.
However, in this case, the function completed its work successfully and need
no action by its caller other than freeing unused bd_holder object. So I
think it's better to return success after freeing by itself.
Otherwise, bd_claim-ing with same claim pointer will fail.
Typically, lvresize will fails with following message:
device-mapper: reload ioctl failed: Invalid argument
and you'll see messages like below in kernel log:
device-mapper: table: 254:13: linear: dm-linear: Device lookup failed
device-mapper: ioctl: error adding target to table
Similarly, it should not add bd_holder to the list if either one of symlinking
fails. I don't have a test case for this to happen but it should cause
dereference of freed pointer.
If a matching bd_holder is found in bd_holder_list, add_bd_holder() completes
its job by just incrementing the reference count. In this case, it should be
considered as success but it used to return 'fail' to let the caller free
temporary bd_holder. Fixed it to return success and free given object by
itself.
Also, if either one of symlinking fails, the bd_holder should not be added to
the list so that it can be discarded later. Otherwise, the caller will free
bd_holder which is in the list.
